My fidget spinner

Hand Spinner with 3 M12 nuts and one 608 ball baring (choose a good one for more fun). You may need an hammer to insert the nuts but go slowly. Very simple and fast to print. Choose a high résolution for best effect.

I post a new version, the precedent one was too loose for the nuts... sorry for this mistake.
I take this opportunity to post a version for two M12 nuts
